35020029

35020029 is a current/voltage monitoring relay with an output. Its application field is mainly to monitor the presence of earth leakage current in industrial power systems. The relay has an automatic system reset inertia when enabled. If the earth leakage current is larger than the preset threshold, the relay will activate an output signal. This process is very critical as the earth leakage current affects the safety of personnel and the electrical devices connected to the power source.

The 35020029 relay works with two voltage inputs and one current input. The voltage inputs monitor the line voltage and the ground voltage. When there is a difference between the two levels, the relay is activated and an output is sent. The current input is used to measure the earth leakage current. When the earth leakage current exceeds the preset threshold, the relay activates and sends an output signal.

The relay contains two configurable elements that can be adjusted according to the requirements. These elements are the minimum and the maximum current thresholds. The minimum current threshold is used to set the minimum current level that needs to be present in order for the relay to activate. The maximum current threshold is used to set the maximum current level that the output will activate. That way, it is possible to limit the extent of the earth leakage current that will cause the relay to be activated.

The relay also has an output which is controlled by the settings of the configurable elements. The output is an alarm signal that alerts personnel in case of excessive earth leakage current. The output can be used to disconnect the power source or activate an additional warning system. Additionally, the output can be used to reset the system or switch on the main circuit breaker. This way, the personnel is alerted in due time to take the necessary precautions.

In conclusion, the 35020029 current/voltage monitoring relay with an output is mainly used in industrial power systems. It works by measuring the voltage inputs and the earth leakage current to activate an output when necessary. The relay contains two adjustable elements that are used to set the minimum and maximum thresholds according to the requirements. It also has an output signal that can be used to disconnect the power source or reset the system in case of an emergency.
